I have a 486DX 66mhz which I am thinking of using as a firewall/gateway in a
similar manor. Unfortunately I live in the country and have to use a dialup
connection. At the moment I have a pentium 200 mhz which is serving as the
firewall/gateway, but I would like to use it for something else as it seems a
waste to use just for the gateway.
I understand that there will always be some sort of overhead when using a
firewall. My question is - will I notice a difference if I switch from a
pentium 200 to a 486 66 as my gateway. I thought that because I am on dialup
that I may not even notice the difference due to the fact that so little
throughput is happening (4-5K a second).
Could anyone tell me if I should expect to see a difference????
thanks
